How does Robert Whittaker cut weight for light heavyweight fights?

Robert Whittaker told Joe Rogan that he walks around at about 106 kilos and starts a camp at about 103. He gets down to roughly 220 pounds and then cuts the last 15 pounds in a warm bath in about an hour and a half. He prefers the bath because he can lie still, rest and listen to music. Running or hitting pads while dehydrated wears him out, and long sauna sessions can dry out and burn his oesophagus.

• Whittaker learned to cut weight the old wrestling way, running long distances wrapped in sweats, because there was little information available when he started.
• Whittaker said he now water-loads mostly out of superstition because he cannot tell whether it actually works.
• Whittaker said he has never used one of the specialist weight-cutting coaches who monitor sodium and water intake.
